In February, Alec had 1,562 visitors to his website. In March, he had 1,310 visitors to his website. What is the percentage decr
1 answer:
Answer:
16.1% is the percentage decrease.
Step-by-step explanation:
We are given the following in the question:
Visitors in February = 1,562
Visitors in march = 1,310
We have to find the percentage decrease of the number of visitors to Alec's website from February to March.
Percentage decrease =
Thus, 16.1% is the percentage decrease in the number of visitors to Alec's website from February to March.

Answer:
Probability that the company wins project A or project B is 0.50.
Step-by-step explanation:
We are given that a company is bidding on two projects, A and B. The probability that the company wins project A is 0.40 and the probability that the company wins project B is 0.25.
Also, Winning project A and winning project B are independent events.
Let the Probability of winning project A = P(A) = 0.40
Probability of winning project B = P(B) = 0.25
<u>Now, as we know that ;</u>
Probability that the company wins project A or project B =
So, we have to find the value of Probability of winning project A and B, i.e;
<em>Since, we are given that Winning project A and winning project B are independent events which means when this condition is given then;</em>
= 0.40 0.25 = 0.10
Now, Probability that the company wins project A or project B is given by;
= 0.40 + 0.25 - 0.10
= 0.65 - 0.10 = 0.55
Hence, probability that the company wins project A or project B is 0.50.
Answer:
Ö + θ ( (k/m) + (g/l)) = 0
Step-by-step explanation:
Use the FBD attached:
Apply Newtons 2 nd Law in tangential direction:
Sum ( Ft ) = m*a
Sum of all tangential forces is:
m*g*sin(θ) + k*l*sin(θ)*cos(θ) = - m*l*Ö
Using small angle approximations:
sin (θ) = θ
cos (θ) = 1
Ö = angular acceleration.
m*g*θ + k*l*θ = -m*l*Ö
Ö + θ ( (k/m) + (g/l)) = 0
